🔍 Key Concepts

• Liftboat operations and stability during jacking • Importance of securing loose gear on deck before major operations • Risks to personnel and small boats alongside when a vessel changes draft or position

💭 Think About

• When a liftboat starts jacking, what changes physically about the vessel’s draft, trim, and movement that could affect items on deck? • Which action, if not done, could most directly create a hazard to stability, equipment, or people as the legs go down and the hull begins to lift? • Think about standard good seamanship: before any heavy evolution (like jacking, anchoring, towing), what is the basic precaution taken on deck?

✅ Before You Answer

• Verify which option best addresses securing the vessel and its equipment rather than just comfort or convenience for crew. • Consider which choice reduces the chance of objects shifting or falling when the hull starts to move relative to the water. • Check which action would be considered a standard pre‑evolution safety practice on almost any working vessel.
